I have a similar concern. I am hoping that I and both my daughters will be playing. All three of us played in KC in 2009 and they had bus transportation set up for junior players. There was a per-student fee and I just dropped them off at the host hotel and they were bussed to and from their course for that day. It worked out very well, but the pools were set up so that both of them were always at the same course at the same time.
From what I have seen, the three of us may be playing three different courses at the same time or times very close together. Are plans being made for transportation needs for junior players? Thank you!
